LIQUID CONTAINER Filed Aug. 16, 1927 2 Sheets-Sheet 2 Patented Oct. 22, 1929 UNITED STATES ROBERT DELTHEIL, OF TOULOUSE, FRANCE LIQUID CONTAINER Application led August 1G, 1927, Serial No.

The present invention relates to liquid containers and, more particularly, to those to be used for containing vaporizable liquids such as perfumes, insecticides and the like.

One of the objects of the invention is to provide a form of container which may be kept sealed and which gradually liberates the volatile liquid contained therein.

A further object is to provide a container 1o and means for controlling the evaporation of liquid therefrom.

Additional objects vvill appear in the course of the detailed description now to be given With references to the accompanying draw-- ings, in which Fig. l is an elevation of one form of container constructed in accordance with the in vention;

Fig. 2 shows the container represented in Fig. l, in section;

Fig. 7 is a section through a fourth form of the invention adapted for pocket use;

Fig. 8 is a section representing a variant ofthe form of invention illustrated in Figs. 1 and 2;

Fig. 9 shows, in perspective, a container arranged so as to distribute perfume to cigaretes kmounted in a common case therewith; an

Fig. 10 is a section through a form of container adapted to be carried in a pocket.

Referring to the Figures l to 4 and 8 of the drawing, there is shown a bottle or container a having a neck portion Z9 fitted With a stopper c. Container a is provided with one or more capillary orifices f which communicate With a porous plate l mounted outside of (Figs. l to 4) or in a recess formed in (Fig. 5) the Walls of container a. The porous material may be felt, pumice stone, unglazed porcelain or any equivalent permeable material. In act-ual practice, unglazed porcelain is 50 found to give the best result.

ment Z may be left bare, as in the modification shown in Figs. l and 2, or covered With a perforated plate t serving to simultaneously diminish the evaporation and to protect element CZ against breakage, as in the modification represented in Figs. 3 and 4. If

it be desired to provide means for regulating the rate of evaporation plate 7L may be covered by a second perforated plate z' (Fig. 8). By sliding plate c' relative to plate 71, any de- 60 sired portion of element d may be exposed for evaporatipn.

llhe modification shown in Figs. 5 and 6 differs from those shown in Figs. l to 4 only in the absence of capillary f. In this form of the invention, porous element d forms part of the container Wall and communicates directly with the container contents. The device shown in Fig. 7 is a variant of that shown in Figs. 5 and 6, with porous element Z forin- 70 ing part of the body of the stopper.

Fig. 9 shows how the container may be mounted With an article to be perfumed ,7ccigarettes-in a common receptacle y'.

The form of device shown in Fig. l0 is in- 75 tended for pocket use. The neck portion Z) of container a is here fitted with a stopper m provided with. capillary f. The porous element CZ is mounted on stopper m and is protected by perforated screen 7L. This form 80 of device functions in the same Way as those already described.

It is important that oriices 7", shovvn in certain of the figures, be true capillaries so that the flovv of liquid to the porous element 35 be not excessive. When the container is to be used to evaporate a disinfectant and a rapid rate of evaporation is desired, the area of plate CZ should be increased and the number of capillaries increased in porportion to the increased evaporating surface employed.

What I claim is l. In a device for diffusing volatile liquids,

a container having a capillary orifice formed in a Wall thereof, and a poro-us evaporating element mounted on said container in com-r munication with said capillary orifice.

2. In a device for diffusing volatile liquids,

a container having a capillary orifice formed in a Wall thereof, a porous evaporating ele- 109 ment mounted on said container in cornmunication with said capillary orifice, and means for diminishing the evaporation from said porous element.

8. In a device for diffusing volatile liquids, a container having a capillary orice formed in a Wall thereoffagvp-orous evaporating element mounted `on-rsaid"container in communication With said capillary orifice,.and a perforated screen coveringrat least ,Apart of said porous element.

4f. In a device for diffusing volatile liquids, a non-porous container having a capillary orifice -linf-a-Wall=v thereof, and a porous `element obstructing saidoriicc.

5.; In combination, ia' 'containenhaving a 'capillary-A opening in za'vvall thereof," and' a 'pj'rjigidj porous element "obstructing Vsaid open- -inglan'd adaptcd'to remove a-liquid inside c my, hand.

-.6. In combination, va container havinga capillary opening 'inf awall thereof, a; porous element Yp'obst'ructing' said opening, and means for"va`rying' the evaporation'of liquid from i f said porous element. Y
